Download RTSA C++ API v1.6.0 release package

1 Introduction 

This document describes the minor release versions 1.6.0 of the C++ language application programming interface (API) for ThinkRF Real-Time Spectrum Analyzer (RTSA) products. See the “Change Log.txt” included in the release package for the record of the current and past releases. 

The release package consists of Microsoft Windows Dynamic Link Libraries (DLLs, suitable for both 32-bit and 64-bit software), its *.lib version and the DLL interface header file wsaInterface.h. 

This version is compatible with the following RTSA products with the associated models 408, 408P, 418, 427: 

  • R5500 / R5550 / R5700 / R5750 
  • Legacy products WSA5000 

See the API Reference Guide included in the “Documentation” folder of the release package for usage and function details. 

2 Fixed Defects 

The following issues are fixed in this version: 

  1. None 

3 New Features 

The following new features and capabilities were added: 

  1. Added 3 new high-level functions related to manual sweep setup (not for use with sweepdevice feature). 
    1. wsaManualSweepStart() 
    2. wsaManualSweepStop() 
    3. wsaCapturemanualSweepTraceAndContext() 

4 Other Changes 

The following other changes were made: 

  1. Added C API v3.8.5 release, which included these changes: 
    1. fixed a bug when sweep is in DD only mode. 
    2. set the sweep start frequency back to 9kHz. 

5 Known Issues and Limitations 

The following are the known limitations or other issues present in this version: 

  1. No Windows Properties information is available for the DLL. 
  2. Usage of some sweep's RBWs (such as 2kHz) for wsa_capture_power_spectrum() could result in a slow sweep (when compared to 1kHz) due to the FFT function usage that is not optimized for non-power of 2 FFT length. Hence, when RBW values that give raise to FFT length at or closer to power of 2, the sweep data processing will be more optimal.
